Newplast™ is a non-drying, non-setting modelling material. It is virtually identical to Plasticine, and can be re-used many times. Newplast™ is sufficiently pliable to make a wide variety of models, but is firm enough to retain its shape indefinitely. Newplast™ is the material specified by most animators as being the only fit-for-purpose Plasticine available. Similarly, it is used extensively in industry, for a wide variety of applications ranging from construction to medical device manufacture.

Newplast is also suited for use in mould & plug creation / sealing / filling.
